SPECIFICATION forming part of Letters Patent No. 271,058, dated January 23, 1883.

Application filed August 18, 1882. (No model.)

To all whom it may concern Be it known that I, FREEMAN J. GEISSIN- GER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an lmproveinentin Roofs.

My invention has reference to roofs and their cornices; and it consists in constructing the cornice-brackets in the form of chimneys or ventilators which extend above the roof and are in communication with the loft, and in many details of construction, all of which are fully set forth in the following specification and shown in the accompanying drawings, which form part thereof.

Ventilators have been arranged on the pinnacle of the roof or ridge, with openings into the loft, but they in no wise formed part of the cornice work, and have never been arranged so as to ventilate flat roofs and thoseinwhich fire-walls are used, as in the case of a row of buildings.

The object of my invention is to provide suitable means to create a constant circulation of fresh air through the loft, whereby the said loft may be kept cool, and thereby prevent undue heating of the rooms of the house immediately below said loft, rendering them comfortably habitable even in the Warmest weather.

This invention is particularly adapted to cheaply-built dwellings containing rooms of small size and low ceilings. It is, however, equally adapted to all kinds of buildings, whether residences or not.

In the drawings, Figure l is a front view, part in elevation and part in section, of my improved roof and cornice, the section being taken on line zzof Fig. 2. Fig. 2 is a sectional elevation of same on linear 0c of Fig. 1. Fig. 3 is a sectional plan of same on line y y of Fig. 1, and Fig. 4 is a sectional elevation of part of the ventilator cornice-bracket in which the top is closed by a screen.

Ais the front wall of the building, and A is the rear wall. B is the division or fire wall, and is located between any two buildings.

E is the roof,and maybe constructed in any desired manner, though what is known as the flat roof, as shown, in'which one end is shown as higher than the other, is preferable.

F is the ceiling, and Ithe room or compartment. The loft-space J communicates at its lowest end with the atmosphere by apertures K, below the eaves, or any other equivalent de- Vice.

0 is the cornice, and is preferably made of sheet-iron, and may be secured firmly to the roof E in the usual manner.

D are the cornice-brackets, and are secured to the cornice O and over the upper part of the fire-walls B, but are about four inches wider than the said fire-walls, so as to leave apertures d to connect the loft-space Jwith theinterior'of the brackets D, which are made to act as ventilators. The tops of said brackets are provided with exit-apertures G or g, or both,

or apertures made in any other convenient If desired, an auxiliary circulation of fresh air may be constantly kept up through the bracket by providing the same with a tube, M, at the bottom, or a simple aperture, L, this latter construction being useful to allow the escape of moisture formed by the condensation of vapor in the atmosphere or when the top of the bracket is left open. If desired, the cornice may open directly into the brackets.

It is evident that the details of construction inightbe greatly modified without departing from my invention.

The operation is as follows: As the air in the loft J becomes heated it tends to escape through the apertures 61 into the brackets D and out at the top, fresh air passing into the loft by apertures K. The brackets being made of light sheet-iron, they become heated and increase thecirculation of the air. As the heated air escapes fresh cool air is admitted, thereby ertheless adapted to single buildings, and may be placed on the ends or intermediate thereof, or may be placed upon the upper edge ofFrench roofs.

I do not limit myself to any kind of bracket,

as they are varied with almost every new building; but said bracket must be made to act as a ventilator to be comprehended by my invention.

Having now described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a rooffor a building, the combination, with the loft, of a cornice, the fire-walls, and ventilating-brackets supported by the cornice, the loft communicating with the brackets to allow a free passage of heated air from the said loft up through said ventilating-brackets, substantially as specified.

2. A cornice-bracket made hollow to form a ventilator, and provided with apertures at the top, in combination with a cornice, aroofloft, and air-passages connecting the said loft with the interior of said brackets, substantially as and for the purpose specified.

3. A cornice-bracket made hollow and provided with openings on the top to form a ventilator, in combination with the cornice, the roof, a ceiling, a loft formed by said roof and ceiling, apertures to admit fresh air to said loft, and air-passages connecting the said loft with the interior of said ventilating-brackets, substantially as and for the purpose specified.

4'. The fire-wall, in combination with a cornice-bracket made of sheetmetal, and provided with vent-apertures at the top, the said cornice-bracket being made hollow and wider than the fire-wall to form air-passages between said wall and sides of the bracket, substantially as shown; a

5.. The combination of the loft J, cornice O,

ventilator-bracket D, having apertures at both top and bottom, lines K and d, substantially as and for the purpose specified.

6. The cornice O, ventilating-bracket D, having apertures at the top, fire-wall B, lines or air-passages d, and a loft communicating with said passages, substantially as and for the purpose specified.

7. The combination of ventilating-bracket D, having apertures G at the top, cover or top cap H, fire-Wall B, loft J, cornice O, and passages d, substantially as set forth.

8. The combination of ven'tilating'bracket D, having, apertures at top and a tube, M, at bottom, fire-wall B, loft J, cornice O, and passage-ways d, substantially as set forth.

In testimony of which invention I hereunto set my hand.
